WRENCH.

SPEGIFICATION'forming part of Letters Patent No. 587,624, dated August3, 1897.

Application filed April 16, 1897. Serial No. 632,4;4'7. (N0 model.)

T0 whom it may concern:

Be it known that I, IRA I3. TRIPP, a citizen of the United States,residing atAurora, in the county of Kane and State of Illinois, haveinvented certain new and useful Improvements in Wrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, which will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in sliding-jaw wrenches which shallbe simple and cheap in construction and at the same time very powerfulin operation and easy of manipulation.

The invention also contemplates the combination of several wrenches ofdifferent sizes and conformations. For instance, with the preferred formof adjustable wrench there may be utilized a smaller nipple-wrench andalso an alligator-wrench. Other useful tools may further be combinedwith the improved wrench without affecting its operation orinconveniencing the operator. For example, one of the extremities of thewrench may be so formed into an effective screw-driver, as I shalldescribe.

In order to better understand the nature of the invention, attention isdirected to the accompanying drawings, forming a part of thisspecification, and in which Figure]. is 'a side view of the device, theparts being assembled and shown as in operation. Fig. 2 is a similarview, the parts being slightly separated, as when a nut is beinggrasped; and Fig. 3 isa section taken on the lines 00 0c of Fig. 1.

In all of the several views like parts are indicated by the samenumerals of reference.

The entire device is made of metal, preferably of sheet-steel, stampedto the proper shape. The body portion 1 of the wrench is provided withthe fixed jaw 22, formed integral with it at one extremity, and with theteeth or serrations 3 on one edge extending from adjacent to the jaw toa point near the other extremity of the body. The sliding j aw 4 of thewrench is formed upon one end of the part 5, which is provided withteeth 6, similar to theteeth 3. An operating-lever 7, which isconstructed of a single sheet of metal bent upon itself to the shapeshown, has down wandly-extending legs 8, which straddle the body 1 andare pivoted at 9 to the sliding jaw 4.

The parts beingplaced in the position shown in Fig. 2 can be adjustedupon the nut, which will be firmly engaged between the jaws, the lever7- being held in engagement with the body, as shown in Fig. 1, tothereby retain the teeth 3 and 6 tightly together. This takes place as anatural result of the grasping of the wrench in the hand and effectivelylocks the jaws.

In order to increase the utility of the device, I may grind the end ofthe part 5 down to a sharpened edge, forming a screw-driver 10, whichcan very handily be used when the part 5 is maintained in a position atright angles to the body 1 or is removed therefrom.

An alligator-wrench 11 may also be formed upon the extremity of thebody 1. By cutting away the body within the alligator-wrench anipple-wrench will be formed for turning nuts too small to be readilygrasped by the jaws of the adjustable wrench, and which will furtherincrease the utility of the device.

Having'now described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is as follows: I

In a. sliding-jaw wrench, the combination with the body having the fixedjaw, and having one edge toothed or serrated, of a sliding jaw havingsimilar teeth adapted to engage with those in the body, and alocking-lever carried on the .opposite side of the body from the slidingjaw, having legs straddling the said body and pivoted to the saidsliding jaw, substantially as set forth.

This specification signed and witnessed this 20th day of February, 1897.
